2. Development and validation of an analytical method using High Performance Liquid Chromatography (HPLC) to determine ethyl butylacetylaminopropionate in topical repellent formulations
ABSTRACT Diseases caused by insects are frequent in poor countries, leading to epidemic scenarios in urban areas; e.g., Dengue, Zika and Chikungunya. For this reason, the development of a safe and efficient topical formulation is essential. Ethyl butylacetylaminopropionate (EB) is a mosquito repellent developed by Merck, which is used in products for adults,

3. Active caspase-3 expression levels as bioindicator of individual radiosensitivity
ABSTRACT Several molecules and events involved in cell response to radiation-induced damage have been investigated towards a personalized radiotherapy. Considering the importance of active caspase-3 in the proteolytic cascade that ensures radiation-induced apoptosis execution, this research was designed to evaluate the expression levels of this protein as a

4. Imbalance of Th17 and Treg in peripheral blood mononuclear cells of active tuberculosis patients
Abstract Objective: Maintaining a right balance between Th17 and Treg might be critical to the immunopathogenesis of active tuberculosis (TB). This study aimed to assess whether the Th17/Treg balance is altered in active TB patients. Methods: 250 study subjects (90 active TB patients, 80 latent TB subjects, and 80 healthy controls) were recruited for the s

6. Investigação experimental e analítica do escoamento ao redor de cilindro circular com supressores de VIV. / Experimental and analytical investigation of the flow around circular cylinder with VIV suppressors.
The fluid flow around bluff bodies is one of the main problems in fluid mechanics. The investigations of this phenomenon are based on analytical, numerical and experimental techniques. Each technique presents advantages and disadvantages, being impossible the comprehensive characterization of the flow though only one technique for the majority of body geomet

7. Aplicação da trifluralina no controle da intrusão radicular de tubogotejadores enterrados sob lavoura cafeeira / Application of trifluralin in root intrusion control of subsurface drip under coffee
The objective of this research was to investigate effects of different doses and frequency of application of the herbicide Trifluralin to avoid root intrusion in subsurface drip irrigation in a coffee field during its initial development (6 to 18 months). While the space between rows was 2.5 meters, space between plants was 0.5 meters. A completely randomize

8. Fotossíntese, crescimento e composição química em plantas de Theobroma cacao L. submetidas a diferentes concentrações de silicato de potássio e sua interação com insetos-praga / Photosynthesis, growth and chemical composition in plants of Theobroma cacao L. subjected to different concentrations of potassium silicate and its interaction with insect-pests
The control of insect pests through the use of pesticides, is still the most method used in the cultivation of cocoa. However, due to environmental issues, there need to seek new alternatives of control less harmful the environment and to humans. In this context, silicon is a nutrient that is being used in various cultures, due to its beneficial effects on p

9. Análise fenotípica e funcional de células dendríticas e monócitos, em pacientes com tuberculose pulmonar infectados por helmintos intestinais
The Tuberculosis (TB) remains a global threat to humanity, which no effective vaccine available until now. Epidemiological studies have shown that Mycobacterium tuberculosis (MTB) and helminths are co-endemic in many regions in the world, and that co-infections with these pathogens are frequent. The intestinal helminths infection may be a risk factor to the

10. Xerostomy, dental caries and periodontal disease in HIV+ patients
We studied xerostomy and its correlation with periodontal and dental cavity diseases in HIV patients, through measurement of salivary flow and through variables such as saliva buffer capacity, salivary pH, periodontal index, MDF index, dental carie risk and risk of periodontal disease. One hundred patients were analyzed. They were distributed into two groups

11. AVALIAÇÃO E REFORÇO DAS CONDIÇÕES DE ESTABILIDADE DE TENSÃO EM BARRAS DE TENSÃO CONTROLADA POR GERADORES E COMPENSADORES SÍNCRONOS / VOLTAGE STABILITY ASSESSMENT AND ENHANCEMENT IN VOLTAGE-CONTROLLED BUSES BY SYNCHRONOUS GENERATORS AND COMPENSATORS
After the incidence of some voltage collapses in the energy transmission systems in the world, the voltage security became an issue of great interest in the last years due to the importance of its impact. The phenomenon of voltage stability is due to the excessive active and reactive power flow in the electrical transmission network and has been associated w

12. Possíveis efeitos antineoplásicos e mieloprotetores da Ipomoea carnea e de seu princípio ativo, a suainsonina, em camundongos / Possible antineoplastic and mieloprotective effects of Ipomoea carnea and its active principle swainsonine in mice
Ipomoea carnea is a toxic plant widely distributed in Brazil and other tropical countries. Among its active principles I. carnea has the indolizidine alkaloid swainsonine, which inhibits intracellular enzymes (the lysosomal α-mannosidase and the Golgi mannosidase II) and alters membrane receptors and adhesion molecules. It is known that swainsonine pre
